Analysis of application fields of metal detectors

Analysis of the application field of Kenwei intelligent metal detector Let's discuss the equipment and technology with you. The principle of metal detectors Most metal detectors are composed of two parts, namely the detection head (including the sensor) and the automatic rejection device. Among them, the detection head is the core part, which consists of three coils, and a central emission The coil and two equivalent receiving coils are fixed in the probe head, and the high-frequency alternating magnetic field is generated by the oscillator connected to the radiation coil in the middle, and the receiving coils on both sides are connected to induce a voltage. cancel each other out before the magnetic field is disturbed. Once the metal impurities enter the magnetic field area: the signals output by the two input coils cannot be cancelled, and the metal detector can detect the presence of metal. The uncancelled induced voltage passes through the sensor and is processed by the control system to generate a rejection signal. It is sent to the automatic rejection device to remove metal impurities from the production line. Application of Kenwei Intelligent Metal Detector Pipeline type metal detector Some liquid and viscous products (such as some oral liquids, health care products) can not meet the sensitivity requirements for detection after canning, and the formula of the products is different. The machine often makes false exclusions, resulting in unnecessary waste. If a pipeline metal detector is used, liquid or viscous drugs are detected before canning, which can effectively improve the detection sensitivity, remove metal impurities online, and ensure that such products are Safe to leave the factory, equipped with rejection devices generally include: extrusion spherical type, three-way type and so on. Tunnel-type metal detector The most common metal detector equipment on the market is the tunnel-type metal detector. This type of metal detector is mainly for online inspection of finished and semi-finished products, and provides final inspection before shipment. The packaging requirements of metal detectors for free fall detectors are that they cannot contain metal, but many manufacturers use metal composite films for packaging considering the tightness of the packaging and high requirements for light protection. However, the metal composite film itself is metal, so the detection sensitivity of the tunnel metal detector will have a large deviation. In this way, we can only choose to detect it before packaging. The free fall type gold detector was developed for the above situation. It is mainly used for the detection of tablets, capsules and granular and powdery items. When a large number of these items fall through the free fall type gold detector, it will use the It is equipped with a quick-start electromagnetic drive lift-type or steering-type rejection device, which can reliably separate contaminated products. This model has the characteristics of simple installation, high sensitivity, convenient maintenance and high efficiency. During the production and processing of medicines, metal powders, particles, needle-shaped amorphous and other metal foreign bodies are often mixed into the products due to equipment wear, manual negligence and other reasons, which brings great harm to the safety of medicines, thus affecting the production of medicines. The reputation of the company has caused great losses. Therefore, we often use metal detectors to detect products to prevent the existence of foreign metal objects in the products.
